Objective:To evaluate the safety of double and a half layered esophagojejunal anastomosis in radical gastrectomy.Methods:This prospective, multi-center, single-arm study was initiated by the Affiliated Cancer Hospital of Zhengzhou University in June 2021 (CRAFT Study, NCT05282563). Participating institutions included Nanyang Central Hospital, Zhumadian Central Hospital, Luoyang Central Hospital, First Affiliated Hospital of Henan Polytechnic University, First Affiliated Hospital of Henan University, Luohe Central Hospital, the People's Hospital of Hebi, First People's Hospital of Shangqiu, Anyang Tumor Hospital, First People's Hospital of Pingdingshan, and Zhengzhou Central Hospital Affiliated to Zhengzhou University. Inclusion criteria were as follows: (1) gastric adenocarcinoma confirmed by preoperative gastroscopy;(2) preoperative imaging assessment indicated that R0 resection was feasible; (3) preoperative assessment showed no contraindications to surgery;(4) esophagojejunostomy planned during the procedure; (5) patients volunteered to participate in this study and gave their written informed consent; (6) ECOG score 0–1; and (7) ASA score I–III. Exclusion criteria were as follows: (1) history of upper abdominal surgery (except laparoscopic cholecystectomy);(2) history of gastric surgery (except endoscopic submucosal dissection and endoscopic mucosal resection); (3) pregnancy or lactation;(4) emergency surgery for gastric cancer-related complications (perforation, hemorrhage, obstruction); (5) other malignant tumors within 5 years or coexisting malignant tumors;(6) arterial embolism within 6 months, such as angina pectoris, myocardial infarction, and cerebrovascular accident; and (7) comorbidities or mental health abnormalities that could affect patients' participation in the study. Patients were eliminated from the study if: (1) radical gastrectomy could not be completed; (2) end-to-side esophagojejunal anastomosis was not performed during the procedure; or (3) esophagojejunal anastomosis reinforcement was not possible. Double and a half layered esophagojejunal anastomosis was performed as follows: (1) Open surgery: the full thickness of the anastomosis is continuously sutured, followed by embedding the seromuscular layer with barbed or 3-0 absorbable sutures. The anastomosis is sutured with an average of six to eight stitches. (2) Laparoscopic surgery: the anastomosis is strengthened by counterclockwise full-layer sutures. Once the anastomosis has been sutured to the right posterior aspect of the anastomosis, the jejunum stump is pulled to the right and the anastomosis turned over to continue to complete reinforcement of the posterior wall. The suture interval is approximately 5 mm. After completing the full-thickness suture, the anastomosis is embedded in the seromuscular layer. Relevant data of patients who had undergone radical gastrectomy in the above 12 centers from June 2021 were collected and analyzed. The primary outcome was safety (e.g., postoperative complications, and treatment). Other studied variables included details of surgery (e.g., surgery time, intraoperative bleeding), postoperative recovery (postoperative time to passing flatus and oral intake, length of hospital stay), and follow-up conditions (quality of life as assessed by Visick scores).Result:[1] From June 2021 to September 2022,457 patients were enrolled, including 355 men and 102 women of median age 60.8±10.1 years and BMI 23.7±3.2 kg/m2. The tumors were located in the upper stomach in 294 patients, mid stomach in 139; and lower stomach in 24. The surgical procedures comprised 48 proximal gastrectomies and 409 total gastrectomies. Neoadjuvant chemotherapy was administered to 85 patients. Other organs were resected in 85 patients. The maximum tumor diameter was 4.3±2.2 cm, number of excised lymph nodes 28.3±15.2, and number of positive lymph nodes five (range one to four. As to pathological stage,83 patients had Stage I disease, 128 Stage II, 237 Stage III, and nine Stage IV. [2] The studied surgery-related variables were as follows: The operation was successfully completed in all patients, 352 via a transabdominal approach, 25 via a transhiatus approach, and 80 via a transthoracoabdominal approach. The whole procedure was performed laparoscopically in 53 patients (11.6%), 189 (41.4%) underwent laparoscopic-assisted surgery, and 215 (47.0%) underwent open surgery. The median intraoperative blood loss was 200 (range, 10–1 350) mL, and the operating time 215.6±66.7 minutes. The anastomotic reinforcement time was 2 (7.3±3.9) minutes for laparoscopic-assisted surgery, 17.6±1.7 minutes for total laparoscopy, and 6.0±1.2 minutes for open surgery. [3] The studied postoperative variables were as follows: The median time to postoperative passage of flatus was 3.1±1.1 days and the postoperative gastrointestinal angiography time 6 (range, 4–13) days. The median time to postoperative oral intake was 7 (range, 2–14) days, and the postoperative hospitalization time 15.8±6.7 days. [4] The safety-related variables were as follows: In total, there were 184 (40.3%) postoperative complications. These comprised esophagojejunal anastomosis complications in 10 patients (2.2%), four (0.9%) being anastomotic leakage (including two cases of subclinical leakage and two of clinical leakage; all resolved with conservative treatment); and six patients (1.3%) with anastomotic stenosis (two who underwent endoscopic balloon dilation 21 and 46 days after surgery, the others improved after a change in diet). There was no anastomotic bleeding. Non-anastomotic complications occurred in 174 patients (38.1%). All patients attended for follow-up at least once, the median follow-up time being 10 (3–18) months. Visick grades were as follows: Class I, 89.1% (407/457); Class II, 7.9% (36/457); Class III, 2.6% (12/457); and Class IV 0.4% (2/457).Conclusion:Double and a half layered esophagojejunal anastomosis in radical gastrectomy is safe and feasible.

Objective:This study aimed to investigate the viability and safety of a novel defecator in managing rectal fecal impaction.Methods:In a descriptive case series, this new defecator was administered to constipated individuals among the ages of 18 and 80 years who met the diagnostic criteria for rectal fecal impaction and were identified with acute rectal fecal impaction through CT scans. The contraindications for this defecator included: (1) Anal stenosis, acute intestinal obstruction, and intestinal perforation; (2) Concomitant rectal malignant tumors; (3) Coagulation dysfunction, low platelet counts, gastrointestinal bleeding, or other bleeding risks; (4) Patients with severe underlying conditions affecting the heart, brain, lungs, or other systems; (5) Individuals with mental health disorders. Based on these criteria, clinical data from 42 patients with rectal fecal impaction who underwent treatment with the new defecator at Deyang People's Hospital between July 2020 and April 2023 were retrospectively analyzed.The defecator comprises three components: a head, a spiral rod, and a handle, constructed from disposable stainless steel wire. The treatment procedure involves the following steps: The patient assumes a flexed, supine position on their left side with their buttocks slightly protruding from the bed's edge. A transparent sealing bag is affixed to the buttocks, centered around the anus. With gloved hands inserted through the bag's entrance, a cotton ball soaked in liquid paraffin lubricates the anal canal and the head of the defecator's spiral rod. The defecator is then slowly rotated and inserted into the anus, with careful attention to any changes in resistance. Once the spiral rod is fully inserted, the patient is instructed to inhale and defecate while the defecator is slowly withdrawn, carrying the dislodged fecal matter, and depositing it into the sealed bag. This operation is repeated 2 to 3 times, followed by the injection of either 100 ml of 36°C normal saline or 60 ml of liquid paraffin into the rectum. After a 5 to 8-minute wait, the patient assumes a squatting position to expel any remaining feces from the rectum. The study assessed the operation time, single treatment success rate, pain levels during treatment, and the occurrence of complications.Results:All 42 patients successfully underwent treatment with the new defecator device, achieving a single treatment success rate of 100%. The average operation time was 11.0 minutes (range: 9.0 to 13.3 minutes). During treatment, 20 cases (47.6%) reported moderate to severe anal pain, with 1 case (2.4%) experiencing anal fissure bleeding, and 6 cases (14.3%) reporting discomfort such as palpitations and sweating. No serious complications, including rectal perforation, were observed in any case.Conclusion:The new defecator device demonstrates ease of use and safety, making it a feasible option for treating acute rectal fecal impaction.

ObjectiveTo investigate the efficacy and safety of ¹²⁵I intraluminal irradiation combined with lenvatinib in the treatment of progressive extrahepatic cholangiocarcinoma. MethodsA retrospective analysis was performed for 25 patients with progressive extrahepatic cholangiocarcinoma who attended Department of Interventional Radiology， The First Affiliated Hospital of Zhengzhou University， from January 2018 to November 2021， and according to the treatment modality， they were divided into combination group with 13 patients （¹²⁵I intraluminal irradiation combined with lenvatinib） and control group （¹²⁵I intraluminal irradiation alone）. The two groups were compared in terms of technical success rates， changes in liver function， stent patency， survival time， and incidence rates of adverse events. The independent－samples t test was used for comparison of normally distributed continuous data between two groups， and the Wilcoxon rank－sum test was used for comparison of continuous data with skewed distribution between two groups； the Fisher’s exact test was used for comparison of categorical data between groups. The Kaplan－Meier method and the log－rank test were used to evaluate survival time and stent patency. ResultsAll patients had successful implantation of biliary stents and ¹²⁵I particles， with a technical success rate of 100%. After 1 month of treatment， both groups had significant improvements in the serum levels of total bilirubin， direct bilirubin， alanine aminotransferase， and aspartate aminotransferase （all P<0.05）. There were significant differences between the control group and the combination group in the duration of stent patency （7.0 months vs 9.5 months， P=0.022） and median survival time （11.5 months vs 15.6 months， P=0.008）. There were no intolerable adverse events in the combination group during treatment. ConclusionCompared with ¹²⁵I intraluminal irradiation alone， ¹²⁵I intraluminal irradiation combined with lenvatinib has better efficacy and is a safe and effective treatment regimen for progressive extrahepatic cholangiocarcinoma.

OBJECTIVES: Staphylococcus epidermidis (S. epidermidis) is a Gram-positive opportunistic pathogen that often causes hospital infections. With the abuse of antibiotics, the resistance of S. epidermidis gradually increases, and drug repurposing has become a research hotspot in the treating of refractory drug-resistant bacterial infections. This study aims to study the antimicrobial and antibiofilm effects of simeprevir, an antiviral hepatitis drug, on S. epidermidis in vitro. METHODS: The micro-dilution assay was used to determine the minimal inhibitory concentration (MIC) and minimal bactericidal concentration (MBC) of simeprevir against S. epidermidis. Crystal violet staining assay was used to detect the biofilm inhibitory effect of simeprevir. The antimicrobial activity of simeprevir against S. epidermidis and its biofilm were explored by SYTO9/PI fluorescent staining. The combined effect between simeprevir and gentamycin was assessed by checkerboard assay and was confirmed by time-inhibition assay. RESULTS: Simeprevir showed significant antimicrobial effects against S. epidermidis type strains and clinical isolates with the MIC and MBC at 2-16 μg/mL and 4-32 μg/mL, respectively. The antimicrobial effects of simeprevir were confirmed by SYTO9/PI staining. Simeprevir at MIC could significantly inhibit and break the biofilm on cover slides. Similarly, simeprevir also significantly inhibit the biofilm formation on the surface of urine catheters either in TSB [from (0.700±0.020) to (0.050±0.004)] (t=54.03, P<0.001), or horse serum [from (1.00±0.02) to (0.13±0.01)] (t=82.78, P<0.001). Synergistic antimicrobial effect was found between simeprevir and gentamycin against S. epidermidis with the fractional inhibitory concentration index of 0.5. CONCLUSIONS Simeprevir shows antimicrobial effect and anti-biofilm activities against S. epidermidis.

Objective:To investigate the clinical significance of excessive inlet view in fluoroscopy-assisted placement of sacroiliac screws.Methods:Included for this prospective study were 47 patients with unstable pelvic fracture who had been admitted to Department of Orthopaedic Trauma, Xi'an Honghui Hospital between January 2020 and January 2021. There were 30 males and 17 females, with a mean age of 39.4 years (from 25 to 66 years). By the Tile classification, 21 fractures were type B and 26 ones type C. The inlet view and the angle of excessive inlet view were measured before operation. The intraoperative placement of sacroiliac screws was assisted by C-arm fluoroscopy navigation in the excessive inlet view. The positions of sacroiliac screws were verified by CT or O-arm fluoroscopy after operation. The screw placement time, fracture reduction quality, fracture healing time, and pelvic function at the last follow-up were recorded.Results:A total of 67 screws were implanted in the 47 patients, including 56 sacroiliac screws. The insertion time for each screw averaged 19.9 min (from 9 to 31 min); the angle of excessive inlet view averaged 17.38° (from 12.1° to 24.8°). Verification by O-arm fluoroscopy or CT revealed that all sacroiliac screws were located in the sacral canal without dislocation or breaking through the cortical bone. By the postoperative Matta scoring, the reduction was excellent in 22 cases, good in 17, acceptable in 6, and poor in 2, giving an excellent to good rate of 83.0%(39/47). The average follow-up time for the 47 patients was 9.5 months (from 5 to 15 months); fracture healing time averaged 10.5 weeks (from 7 to 16 weeks). By the Mejeed scoring at the last follow-up, the pelvic function was excellent in 26 cases, good in 15 and acceptable in 6, giving an excellent to good rate of 87.2% (41/47).Conclusions:Fluoroscopy in the excessive inlet view is a simple and easy intraoperative technique. It can improve accuracy and safety of sacroiliac screw placement because it allows clear identification of the posterior border of the sacrum and effectively avoids iatrogenic injury to the sacral nerve caused by screws breaking through the bone cortex.

Objective:To summarise the advantages and disadvantages of applying the method of retrograde replantation with an operative position of foot stepping and knee bending for replantation of rotational avulsed and fractured great toes.Methods:From January 2016 to June 2021, 11 rotational avulsed and fractured great toes were replanted with the method of retrograde replantation in an operative position of foot stepping and knee bending. Of the 11 patients, 10 were males and 1 was female, aged 18 to 50 years old with an average of 32 years old. Causes of injury: 5 of driving belt, 4 of machinery crush and 2 of car accident. Injury sites: 4 on left great toes and 7 on right great toes. All of the injuries were with fracture and exposure of proximal tendons of flexor and extensor. Seven patients had the follow-up reviews by outpatient clinic visiting, 2 over mobile phone and 2 via WeChat.Results:After surgery, 9 great toes completely survived and 2 great toes had necrosis. The survival rate of toe replantation was 81.8%(9/11). The operation time was 2 to 3 hours, with an average of 2.5 hours. Postoperative X-ray film showed that 8 to 12 weeks after the operation, the fracture and joint fusion were healed at first stage in the survived toes. All patients were entered in follow-up for 3 to 18 months with 10.5 months in average. The survived great toes were plump and the toenail grown well. At the final follow-up, the static TPD at the toes was 8-12 mm, with an average of 10 mm. There was no effect shown on either walking or running.Conclusion:The retrograde replantation method with an operative position of foot stepping and knee bending for great toe replantation has the characteristics of a good field of view and convenient in operation under microscope, a short operation time, and a high survival rate of replantation.
